Gave blood today for the Red Cross. I have been a fairly regular donor since high school. Today was my 19th donation. At 24 I get a 3 gallon pin.
For some reason when they stopped the flow to the bag so they could get some in the test tubes the bevel at the end of the needle sucked up against the edge of the vein. It was rather painful as they worked the needle around to get enough blood to fill the 3 test tubes.
In the end I got a sticker (heart shaped that says “Be nice to me, I gave blood today”), a red bandage, an ice pack, some cookies, and a hematoma on my arm. Hematoma is basically medical speak for bruise.
